You should be able to do that through the vac hose hookup with an allen wrench. I have never done it .. but will be doing it for the first time on an RV project I have.

i think the allen screw was used on stock 318's in 68 or 69. you might find an aftermarket unit that will do this.

I think that ALL kits and separate distributors that MP sells has that feature. And this even includes the /6 !!

I have never seen a "chart" .... just do it by trial-and-error.

you could use a timing light to measure the before and after results.
